Description
The operational experiences from the 2006 measurement campaign with REX-
ISOLDE will be presented. This year a number of new beams were accelerated;
a record beam energy of 3.1 MeV/u was achieved; successful charge breeding
of elements with A>200 was demonstrated; the ion pulse could be extracted
slowly from the EBIS; isobaric separation inside the REXTRAP was proven
feasible with a new cooling and excitation scheme; the electron beam current
inside the EBIS reached a record value of 460 mA; and the transverse
emittance after the linac was accurately measured among other development
efforts. The first phase of the REX upgrade is well underway. The Miniball
experiment is moved into the new hall extension and modifications of the
beamline layout are carried out in order to improve beam quality and
measurement conditions at the experimental targets. This is the first step
towards a more ambitious upgrade program including a possible
superconducting linac for higher beam energies in the framework of HIE Isolde.
